IMS组网策略研究

IMS(IP多媒体子系统)作为业界公认的核心控制层融合技术,在运营商推进网络融合进程中备受关注。通过对IMS规模部署中的组网结构、与其它网络的互通、业务平台建设等方面的研究,建议运营商在IMS的组网结构上,可以依据IMS用户规模和管理机制等因素,以大区或省为单位建设统一的IMS网络;在IMS业务平台建设上,运营商可以依据现有网络情况,灵活选择利用原有业务平台或新建IMSAS来实现业务融合,同时为固网、移动用户提供业务,同时IMS还可满足运营商多媒体业务推广的需求。

IMS Networking Strategy

As the accepted core control level technique, IMS has been paid more attention during the network integration. Through the research on the IMS network architecture, intercommunication and platform construction, the following suggestions were proposed. Carriers could establish province-based unified 1MS network according to the user numbers and mechanism. Carriers could establish new IMS AS or use old platform to realize service integration, providing services for both fixed line and mobile users. IMS could satisfy the requirement for multimedia services development.
